Data ethics & privacy

These datasets follow academic data-ethics practice. Where real-world documents contain sensitive personal data:

Positional Token Masking

In legal deed benchmarks (KhatianDoc), real citizen names are replaced with positional identifiers ([PERSON_1], [PERSON_2]) to protect citizen privacy while preserving multi-hop inheritance co-reference.

Verbatim Reference Extraction

In chemical safety benchmarks (KrishokChat), ground-truth answers are extracted verbatim from official government extension manuals rather than synthetic LLM generation, preventing synthetic error propagation.
